Be thine own palace, or the world's thy jail.
Only the educated are free.
Do not weep do not wax indignant. Understand.
Quality is not an act, it is a habit.
Problems are not stop signs, they are guidelines.
Always desire to learn something useful.
It's always too early to quit.
The secret of getting ahead is getting started.
You never know what motivates you.
Begin to be now what you will be hereafter.
I have taught history on the high school and college levels, and am or have been a lecturer at the Smithsonian, The National Institutes of Health, and numerous colleges and universities, mostly on science fiction and technology subjects.
